Lockout Protection; Liftgateiliftglass - GMC 2003 Yukon Denali User Manual

Lockout Protection
This feature protects you from locking your key in the
vehicle when the key is in the ignition and a door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will
lock and then the driver's door will unlock.
Liftgate/Liftglass
It can be dangerous to drive with the liftgab- or
liftglass open because carbon monoxide (CO)
gas can come into your vehicle. You can't see
or smell CO. It can cause unconsciousness
and even death. If you must drive with the
liftgate open or if electrical wiring or other
cable connections must pass through the seal
between the body and the liftgate or liftglass:
Make sure all other windows are shut.
